Dust Volume 5, Number 5

PUP

Home fi, gnawa-pop fusion, mariachi cowpunk, classically minded jazz, shout-y punk-pop and finger picked acoustic blues—as appropriate for spring, Dust lets a thousand flowers bloom.This edition of short, mostly positive reviews, draws contributions from Isaac Olson, Bill Meyer, Jennifer Kelly and Justin Cober-Lake. We hope you find something to blast from open windows on the first warm, sunny opportunity.

Ahmed Ag Kaedy — Akaline Kidal (Sahel Sounds)

Akaline Kidal by Ahmed Ag Kaedy

This acoustic, solo release by Malian guitarist in exile Ahmed Ag Kaedy is a beaut. Like a lot of so-called desert blues, this is only chill out music until you read the lyrics, for example, “The Tuareg people must know/you can consider France an enemy/no better than Algeria who stands in our path.” Even if militant nationalism, no matter who’s calling for it, isn’t your thing, Ahmed Ag Kaedy’s weathered, throaty voice and plangent, monophonic guitar flights which are as evocative, bitter, and seemingly ephemeral as campfire smoke, make Akaline Kidal well worth hearing. And like campfire smoke, they’ll stick with you well into the next day.

Astralingua — Safe Passage (Midnight Lamp)

Safe Passage by Astralingua

Quietly, precisely odd, this elaborately instrumented, baroquely arranged folk experiment shrouds whispery threads of poetry in eerie landscapes of stringed instruments, pennywhistles and gently massed harmony. The music, mostly the work of composer Joseph Andrew Thompson but aided by singer Anne Rose Thompson, runs much in line with goth folk outfits like Gravenhurst and Boduf Songs, in the way that dread seeps up from the floorboards and beauty has a spectral, semi-transparent air; you could make a case for an Elliott Smith singing in front of Clogs comparison in a couple of the songs. Yet the music faces forward, not back into misty folklorics. “Space Blues” takes a turn towards proggy Pink Floyd-ish visions of interstellar travel on “Space Blues” and while “Poison Tree” heads off into to tremulous orchestral confessionalism, a la Sufjan Stevens. It is all very pretty and a little disturbing.

Kaja Draksler / Petter Eldh / Christian Lillinger—Punkt.Vrt.Plastik (Intakt)

Punkt.Vrt.Plastik by Kaja Draksler, Petter Eldh, Christian Lillinger

This pan-Euopean combo rethinks one of the most cobweb-festooned configurations in jazz. To overcome the piano trio’s over-familiarity, they combine idiosyncratic personal techniques with a disciplined collective approach. Swedish bassist Petter Eldh and German drummer Christian Lillinger have forged their concord in a couple other groups; the former is assertively melodic and big-toned, the latter quick and ubiquitous. With so much happening in the engine room, they need a partner who values balance, and they have found one in Slovenian pianist Kaja Draksler. Her playing is fleet and articulate, and her ideas feel complete in themselves, but they also leave ample space between the root notes for her partners to exercise their formidable muscles without banging into any harmonic walls.

Maxine Funke — Home Fi (Feeding Tube)

home fi by maxine funke

Keep your lo fi, hi fi, and wifi; Home Fi is where it’s at. Really, how come no one characterized their music thusly before? Maxine Funke’s songs flesh out the conceit with lyrical details that relate not just home life, but a state of at-homeness on the grounds around the house. “February” doles out images of late summer foliage (Funke lives in New Zealand) and foraged taste treats; “Waving the Tea Rose” finds spiritual riches in the neighbors’ trash. Funke’s accompanies her slightly sleepy croon with spare finger-picking, captured up close enough that you can hear a chair creak while a strategically dissonant organ or fiddle pipes up in the background. This record, which was originally sold as a tape on an Australian tour, lasts just 22 minutes, but it feels as complete as an afternoon nap.

Bill Meyer

Houssam Gania — Mosawi Swiri (Hive Mind Records)

Mosawi Swiri by Houssam Gania

Houssam Gania, son of guimbri master Maalem Mahmoud Gania, opens Mosawi Swiri, his debut, with an act of cheerful patricidal aggression. Rather than launching into the traditional Gnawa music — solid and sparse as a mudbrick house, deep and dark as a well and groovy as ripples in a dune — that his father mastered, Gania’s traditional guimbri and qraqabs are joined on the first track, “Moulay Lhacham,” by a guitar/drums/keys band that sounds not unlike Brent Mydland-era Dead. It’s sunshiny, a little corny and perfectly delightful. Ok, ok, so Gania Sr. was no purist himself, having collaborated with, among others, Pharoah Sanders and Peter Brotzmann, but Gania Jr’s opening gambit is pure pop delight. Luckily for armchair ethnographers everywhere, the rest of Mosawi Swiri sticks to traditional Gnawa music, which in Gania’s capable hands, really is as hypnotic and potentially curative as both locals and marshmallow-eared world music fans claim. That first track is a hoot though, and while I’m not sure Gania could sustain a whole album of gnawa-pop fusion, I’d love to see him try.

A.F. Jones — Bourdon du Kinzie (Unfathomless)

Bourdon du Kinzie by A.F. Jones

Sound ecologist, submarine acoustician, mastering engineer, musician; if it manifests within the ears, A.F. Jones is tuned into it. This CD echoes an order that David Thomas, a man who has never been shy about telling other people what to do, once barked. “Insist on more than the truth.” This album began with a field recording expedition to a disused bunker in Port Washington, WA. The space is simultaneously absorbent and reverberant, luring external sounds into its cavernous interior and transforming them with its long decay times. You could probably get some cool sounds by simply stamping your foot or dropping the change in your pockets and hearing what the space does to it. But sound collection is just the first step for Jones. He’s used audio analysis software to isolate and enhance the space’s dominant tones, and then further seasoned the reduction with dancing sine tones. The result is a sort of sonic centrifuge in which essences are extracted so that some sounds become more ephemeral and others more vivid. Give it a spin.

Bill Meyer

Patio—Essentials (Fire Talk)

Essentials by Patio

All clanks and spikes and spatter, this Brooklyn-based trio constructs a jag-edged punk with lots of space. It jangles like a bag of rusty nails. The vocals—sung sometimes by bassist Loren DiBlasi and other times by Lindsey-Paige McCloy, the guitarist (but not by Alice Suh, the drummer) —are a soothing counterpoint, unless you listen to the words, which are sharp despite the cool, distanced delivery. The band mixes late-1980s post-punk jitter with intriguing intervals of chanted poetry and pop self-revelation. “Open,” the longest cut, threads an antic, literate narrative atop a bassline so crackling with electricity that you could get a shock. “Boy Scout,” the single, bounds ahead then collapses in a heap, surges and stops in sudden uncertainty. The music exactly mirrors the confusing, conflicting emotions sketched in lyrics like, “Never have the chance to choose, naturally I always lose, I went shopping the other day, this week I can afford to feel better.” Patio makes inward-facing music that jerks and spasms in an approximation of hedonism, but maintains its quiet, difficult core.

PUP — Morbid Stuff (Little Dipper/Rise/BMG)

Morbid Stuff by PUP

It’s been a minute since shout-along punk rattled cages like this second outing from Toronto’s PUP. Here in 11 teeth-rattling blasts, the band radiates bratty intelligence and dashed hopes, amid slamming guitars and kit battering drums. The tension between nerdy, needy erudition and beer bro riffs is palpable. When singer Stefan Babcock confesses, “Just like the kids/I've been navigating my way through the mind-numbing reality of a godless existence/Which, at this point in my hollow and vapid life, has erased what little ambition I've got left,” at the beginning of the single “Kids” you kind of expect the guy to get beat up by his own song. Obvious references include the Hold Steady, Green Day, Japandroids, that is, pretty much any punk that smart kids can memorize and dumb kids can punch the air to without really understanding. The trick is to stomp with triumphant, hobnail-studded aggression all over the relentlessly depressing lyrical content. Pretty soon, we are all singing along that, “Just because you’re sad, doesn’t make you special.”

Joshua Redman Quartet — Come What May (Nonesuch)

youtube

Saxophonist Joshua Redman has been one of the defining voices of mainstream jazz for a quarter century, his clear tone and lyrical sensibilities a steady source of pleasure in various configurations. For Come What May, Redman reassembles his quartet from the early 2000s (pianist Aaron Goldberg, bassist Reuben Rogers and drummer Gregory Hutchinson) for seven original compositions. The group stays locked in across a variety of sounds, with Goldberg particularly getting some time to shine. Bookending the album with meditative numbers “Circle of Life” and “Vast” makes for a nice closed structure to the disc, letting the livelier numbers pulse and swing. On “DGAF” the musicians' comfort with each other allows Hutchinson to guide a jerky momentum, one that works best when he reclaims it near the end of the song.

The ensemble doesn't push any obvious boundaries here, despite a few demanding interactions. Redman and his group are locked into standard sounds, with the challenge simply being how well they can do it. Not surprisingly, they're quite good at it, and the fact that Redman's conversations sound so easy shouldn't distract from the high level of play here. The quartet sticks to its tradition with clear sound, strong melodies and smart interplay, playing to its strengths for another expressive release.

Vandoliers—Forever (Bloodshot)

Forever by Vandoliers

Vandoliers, out of Dallas, make punk rock with country fiddles, hoarse-voiced stomp-alongs with Mexicali flourishes of trumpet. “Sixteen Years,” which commemorates how long these urban cowboys have been on the job, sports bruise-y r ‘n r defiance, with its chugging beat, its cigarette-and-whiskey-vocals, but leavens the mix with brash folkloric bursts of brass. A rougher “Troublemaker” amps up the one-two shuffle and slides the cow-punk meter over towards the punk side, while contemplative “Cigarettes in the Rain,” smoulders and smokes much like its subject matter, but with a noticeable twang. Forever reminds you that the Rolling Stones were, on occasion, a country band, and the Replacements once made songs like “Waitress in the Sky.” The line is permeable, the fence has a nice place to sit on, and the Vandoliers are neither punk nor country but both.

Eli Winter — Time to Come (Blue Hole Recordings)

The Time To Come by Eli Winter

With The Time to Come, college student Eli Winter makes his entry into the solo guitar scene. Winter cites Jack Rose as a prominent influence, but he doesn't have the thickness or the pulse of Rose's sound. His sensibility, especially when playing acoustic, lies closer to Glenn Jones in his creation of atmosphere, brightness and storytelling. “Sunrise Over the Flood” starts with a simple, pretty pattern before turning dark, an evocative moment of lightness used to reveal something heavy. On the poppier side, “Oranges and Holly” builds around a riff close to the intro from “Here Comes the Sun,” but it never quite distinguishes itself. The title track unfurls over 15 minutes, Winter's structured thought allowing for linear but engaging progression. Winter's debut makes the case that we should be paying attention to him; he certainly has things to say and has the right vehicle for his expression. At the same time, it feels like a debut. Winter's restraint keeps everything in its right place, but it would be nice to see him challenge himself technically. Taking a few more risks would help him find his own niche the field, a spot he's likely to earn with a little more seasoning, given his smart songcraft and thoughtful aesthetics.

Michael Zerang—THE SHUDDERING CHERUB (Pink Palace Records)

THE SHUDDERING CHERUB - for solo piano with vibrating elements by Michael Zerang

If you’re wondering how Chicago’s improvised music company made the march from the AACM’s rejection of commercial and racial marginalization in the 1960s to the current polymorphous scene, train your antennae on Michael Zerang. He’s one of the people who did the hard work of not just playing but organizing during the long dry 1980s. His polyvalence extends to his musicality; he’s played unamplified and electro-acoustic improvisation, ecstatic drone, indie rock, free jazz and pan-global percussion. It might seem a bit perverse that his first solo recording is on piano, but listen and your befuddlement will pass. Zerang spends precious little time on the keys. Instead he plunges into the instrument’s interior, liberally preparing its strings and then plucking, scraping and vibrating with sure hands and some trusty vibrators. The music morphs like a chameleon’s coloration, shifting from coarse texture to crystalline drizzle.

The Composition Of The Complete Plant Of Ring Roller Mill

The complete plant of ring roller mill is made up of four systems which are the Main engine, powder extraction system, feeding system, and control system (Fig.1). According to the needs of different industries, the material used for making some accessory may choose carbon steel or stainless steel or other material of different quality.

2.1 The configuration of the main engine and the operating principle of the hoop-roller mill

The main engine of ring roller mill mainly includes the crushing system, grading system, power and speed reducer system.

Figure two is the sketch map about the Operating Principle of hoop-roller mill. There is a big space for moving between the grinding hoop and the pin axletree which are installed on the grinding hoop bracket. When the grinding hoop bracket revolves following the principal axletree, the grinding hoop will be thrown towards the grinding circle with centrifugal force and impact the grinding hoop wall. So the grinding hoop can also rotate around the pin axletree. When the material passes the clearance between the grinding hoop and the grinding circle, it will be crushed because of the impact, rolling and grinding by the grinding hoop. The crushed material falls on the material throwing dish with the gravity, and it is thrown to the airflow passage. At the effect of the negative pressure attraction of the systemic fan, the crushed material enters the grading cell following the airflow to be graded. The eligible fine-powder passes the grading wheel, and then goes into BEOL collection system to be collected. Meanwhile, the rough material is thrown onto the wall of the diffluence hoop, and drops into the smashing cell to be crushed over again. The grinding hoop is two-double distributed. When the material passes the clearance between the grinding hoop and the grinding circle of the first floor, it is crushed for the first time. And when it passes the second floor, it is crushed again. So the material is crushed sufficiently. And then the product is fine.

2.2 The extraction system of the powder

The extraction system of the powder consists of the high pressure centrifugal fan, Pulse filter, transporting pipe, closing fan motor and other main components. The eligible crushed powder is extracted from the main engine by the negative pressure which is generated by the high pressure centrifugal fan. After the gas-solid separation by the vortex segregator of the first stage and the air cleaning by the bag-type deduster of the second stage, the depurative air is discharged from the fan outlet. And the collected powder is further mixed by feed screw ,finally discharged from the closing fan motor output.

2.2.1 Bag-type deduster

Bag-type deduster filters the dust-laden gas using the porous fibre filter bags. It can separate the dust which is below 5μm, making the exhaust gas reach the national discharge standard. The HLM series Hoop-Roller Mill uses the pulse blowing-back bag-type deduster. It mainly consists of the cabinet (also called bag house), filter bags, frame and deashing device. Except that the customer requires the material of especial quality, the filter bags usually use the water-repellent and oil-proof punched felt.

The dust-cleaning device of the pulse bag-type deduster consists of the pulse valve, spray-tube, air storage,bag, induction unit (This equipment uses Venturi tube) and control instrument. The compressed air which is the power of the dust-cleaning is supplied by the customers yourselves (For details, see 4.4). All the other devices are supplied by our company in whole set.

2.2.2 Closing fan motor（also called air-lock material-unloading device）

The hoop-Roller Mil uses the convolution-type Closing fan motor which is installed under the vortex separation or the dust catcher ash bucket. It can both discharge the collected powder and prevent from the air outside entering which may affect the separation effect. It mainly consists of the convoluted impeller, crust, cycloid pin gear speed reducer, electrical machine and other parts.

2.2.3 High pressure centrifugal fan

It uses the negative pressure produced by the fan to extract and transport the powder.

2.3 Material feeding system

According to the characteristic of the material, feeding has two types that are screw-feeding and electromagnetic vibrating-feeding. The customers can select any one of them. Screw feed uses frequency conversion to control the feeding quantity. And the electromagnetic vibrating feeder uses the electric vibrating controller to control the feeding quantity. Usually, the screw feed is for the fine powder, and the electromagnetic vibrating feeder is for the material of rough grains.

Material feeding system consists of the central material storehouse, central storehouse bracket, screw feed (or electromagnetic vibrating feeder), control device and other parts. In the running process, the change of the feeding quantity and the running status of the complete set of the equipment interact each other. That makes the output and the product fineness keep in good condition.

2.4 Control system

The control of the Hoop-Roller Mill has two types. That are the hand control and auto control by programmable logic controller（PLC）. It usually uses the hand control. The control principle is showed in figure three (see addenda):

Pulse control instrument is solely installed near the dust catcher. Except that, all the control circuitry and the instruments are installed inside the control cabinet. So the manipulation is convenient.
